Application filed November 19, 1902. flerial no. 131,990. (No model.)

10 ttZZ whom, it may concern:

Be it known that I, GEORGE A. WHITE, a citizen of the United States,residing at Wellsville, in the county of Montgomery and State of Missouri, have invented a new and useful Egg-Testing Device, of which the following is a specification.

This invention relates to devices employed for testing eggs, and has for its object the production of a simply-constructed and easilyoperated device which may be employed without the use of artificial light; and the invention consists in a casing open at one end toward the light and with converging sides, with one or more egg-supporting apertures in the smaller ends, whereby the light entering at the larger opening will be converged upon the eggs protruding through'the apertures.

The invention further consists in a casing open at one end, with its sides converging toward the closed end and provided with eggsupporting apertures at the closed end, the casing adapted to be connected to the in terior of a Window-opening and forming a closure thereto.

The invention further consists in a casing open at one end, with its sides converging toward the closed end and with one or more apertures for supporting eggsf'transversely disposed at the closed end andfwithreverselyinclined reflector-platesadapted to intercept portions of the light-rays anddeflect them upon the eggs protruding through the openlngs. V

Other novel features of the invention will be disclosed in the annexed description and be specified in the claims following.

In the drawings illustrative of the invention, in which corresponding parts are indicated by like designating characters in each of the figures, Figure 1 is a perspective view of the device applied. Fig. 2 is a longitudinal section, enlarged, of the contracted end of the casing. Fig; 3 is'a" longitudinal section on the line III III of Fig. 2.

The improved device will preferably be employed in connection with awindow-opening,

but may be likewise eniployedin connection" with any opening through which a strong natural light will pass, and for the purpose of illustration the device is shown Inovably attached to a wall or other stationary structure, (indicated at 10,) the'wall intended to represent that portion of a buildingimmediately adjacent to a window-opening. The window-opening is not shown in the drawings, as the construction issoywellkn'own.

The device consists ina casing, preferably rectangular in cross-sectionand open at one end, with the open end supported by aframe 11, the latter preferablyhinged to Jthewall 10, as at 12, so that the casing'may be'turned back out of the way whennot inuse; and thus permit the window opening in the ordinary manner.

Intesting eggs it is necessarythat the room he darkened, so that the best resultsmay be obtained from the light, which is caused to pass through the eggs. Hence 'theimproved device will be formed'to entirely closethe window-opening and shut offall light.

The lightdeflecting casing extends inwardly from the frame 11 and is formed with converging sides 13,1ending. at thereducedend 14, as shownl By this arrangement the light-rays entering through the open end of the casing will be deflected and converged toward the smaller closed end 14, as willbe obvious.

The casing will preferably be formed either entirely of ftinned plates or, lined with tin or other reflecting materiaL-soth'at the lightrays will be properly reflected and converged toward the smaller end of the casing.

Formed in the smaller end of the casing 13 will be the egg supportiugapertures 15, any required number being employed. For the purpose of illustration two of the apertures 15 are shown; but any requirednumber may be employed, and I do not wish, therefore,'t0 be limited to any specified number ofthe apertures. Disposed. between the apertures 15 are inclined I reflecting plates 16.17,. the plate 16 adapted to deflect a portion of the light-rays toward the egg supported in one of the apertures and the plate 17 adapted to deflect'portions of the light-rays towardthe egg supported in the other aperture. By this means the intensity of the light thrown a'gainst the eggs protruding through the apertures is materially increased and the effectiveness of the device correspondingly increased.

When the device is employed, all other to be used ICC openings in the room will be closed or the device surrounded by a separate inclosure to shut off all light except what passes through the small openings 15. By this simple arrangement the comparatively large area of the outer open end of the casing receives a correspondingly large volume of light, and this volume of light being converged by the inclined sides 13 upon the comparatively small apertures 15 and the eggs protruding therethrough will at once reveal the condition of the eggs. The reversely-disposed reflecting-plates 16 17 add materially to the intensity of the reflected light thrown upon the eggs, as above noted. By this simple means the eggs are tested without the use of artificial light, and this dispensing with artificial light is a very important feature of the invention and materially increases the value and eliiciency of the device, as the use of artificial light for the purpose of testing eggs is very objectionable, as eggs are usually packed in highly-combustible material, and serious losses are frequently the result of these combustible materials coming in contact with artificial light thus employed. Another advantage gained by the use of this device is that the eyes of the operator are not required to constantly change from light to darkness, as the light passing through the small apertures 15 is comparatively uniform in intensity. Consequently the pupils of the eyes are not constantly and injuriously increased and decreased or expanded and contracted, as in the ordinary egg-testing devices using artificial light.

The apertures 15 will preferably be provided with angular protecting-plates 18, of rubber, felt, leather, or other yieldable substance, with which the eggs come in contact, and thus prevent the breaking of fragile eggshells when the eggs are inserted.

By providing two of the openings 15 one person can test two eggs at the same time, and thus double the capacity of the device, and, if required, a greater number of the apertures may be arranged in the casing to enable two persons to use it at the same time.

The casing may be constructed in any required size andof any suitable material, but, as before'stated, will preferably be constructed to fit an ordinary window-opening and form a closure thereto, so that a special opening device will not be required; but I do not wish to be limited in any manner to the size of the opening or the casing 13. The yieldable packing 18 also serves to prevent the escape of light between the eggs and casing, as will be obvious.

Having thus described the invention, what is claimed is 1. An egg-tester comprising a casing having converging sides lined with a reflecting material and provided near its smaller end with one or more eggreceiving apertures, said casing having its larger end wholly open to the light. and its smaller end closed.

2. An egg-tester comprising a casing having converging sides lined with a reflecting material and provided with one or more eg receiving apertures near its smaller end, said casing having its large end wholly open to the light and its smaller end closed, and converging reflectorplates associated with the closed end of the casing and projecting therefrom into the casing.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

GEORGE A. WHITE.
